Functions of GENESIS

The GENESIS program package is composed of two MD programs (ATDYN, SPDYN) and trajectory analysis tools.

  • MD, Replica Exchange MD (REMD), Energy minimization
  • CPUs+GPGPUs hybrid MD/REMD simulations
  • Highly parallelized PME method
  • Forcefields: AMBER, CHARMM C27 & C36, Go models (Cα, all-atom, and KB Go models), etc.
  • High performance MD simulations of protein solution and membrane systems by CPUs/CPUs+GPGPUs
  • Scalable MD simulations of huge systems (> 100,000,000 atoms) on massively parallel environment (such as K computer)
  • Multi-dimensional REMD calculations; temperature, pressure, surface tension, umbrella sampling
  • String method for most probable pathway search
  • Umbrella sampling, Replica Exchange Umbrella Sampling (REUS), and string method in collective variable space
  • NVE, NVT, NPT, NPAT, NPγT ensembles & Langevin, Berendsen, and Bussi thermostat and barostat
  • Analysis: RMSD, RMSF, PCA, WHAM, MBAR, etc.

MD trajectories obtained by GENESIS can be visualized with VMD and other software. CHARMM-GUI input generator can be used for the preparation of GENESIS input files.

How to cite GENESIS

Any published work which uses GENESIS 1.0 or before might include the reference:

Any published work which uses GENESIS 1.1.x or 1.2.x should cite the following reference:

In computational neural science, there is another GENESIS (General Neuron Simulation System), which has a long history of the development. Our GENESIS has been developed independently in the computational structural biology field.
